20220311946 · 2022-09-29 · ·

A stereoscopic imaging platform includes a stereoscopic camera configured to record left and right images of a target site. A robotic arm is operatively connected to the stereoscopic camera, the robotic arm being adapted to selectively move the stereoscopic camera relative to the target. The stereoscopic camera includes a lens assembly having at least one lens and defining a working distance. The lens assembly has at least one focus motor adapted to move the at least one lens to selectively vary the working distance. A controller is adapted to selectively execute one or more automatic focusing modes for the stereoscopic camera. The controller has a processor and tangible, non-transitory memory on which instructions are recorded. The automatic focusing modes include a target locking mode. The target locking mode is adapted to maintain a focus of the at least one stereoscopic image while the robotic arm is moving the stereoscopic camera.

MINIATURIZED MOBILE, LOW COST OPTICAL COHERENCE TOMOGRAPHY SYSTEM FOR HOME BASED OPHTHALMIC APPLICATIONS

Improved optical coherence tomography systems and methods to measure thickness of the retina are presented. The systems may be compact, handheld, provide in-home monitoring, allow the patient to measure himself or herself, and be robust enough to be dropped while still measuring the retina reliably.

Binocular retinal imaging device, system, and method for tracking fixational eye motion

A binocular scanning laser ophthalmoscope (SLO) is used to track the fixational eye movement of each of the eyes of a subject. The binocular SLO may include right eye optics for imaging a portion of the retina of the right eye and left eye optics for imaging a portion of the retina of the left eye. Shifts in the imaged portion of the retina with respect to a reference image of the retina may be used to measure and track eye movement. The right eye optics and left eye optics may be separate imaging paths, each with its own bi-directional MEMS scanning mirror and Keplerian telescope. The use of the MEMS scanning mirrors minimizes the size and weight of the binocular SLO.

Device for machining an object by application of laser radiation

A device for machining an object by laser radiation, by photodisruption. The device includes an observation device for imaging the object and a laser scanning device by which the laser radiation is passed over a predetermined sector of the object for scanning the sector. The device includes the observation device with a first lens for imaging the object; the laser scanning device with a second lens, through which the laser radiation is guided, in which both lenses with regard to the dimension of the regions to be produced in the images and/or with regard to their focal intercept are different from each other. The device alternately images the respective region of the object in a first operating mode by the first lens and in a second operating mode by the second lens. It is thus possible to use in both operating modes a lens adapted to the intended imaging purpose.
